BUILDING-BLOCK AND WALI...

SPECIFICATION forming part of Letters Patent No. 733,928, dated Jul 14, 1903.

Application filed April is, 1903. Serial to. 153,326. (Nomodelh To all whom it mayconcern: Be it known that I, JOHN ALBERT FERGU- SON, 'a citizen of the United States of Amer-' ica, residing inithe city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Buildfollowing to be a full, clear, and exact dehad to the accompanying drawings, and to the scniption of the invention, such as will enable others skilled-in the art to which it appertains to make and use the same, reference being claimed, all of which will be fully understood 4 by reference to the accompanying drawings,

- intermediate projection A in which is illustratedan embodiment thereof.

In the drawings, Figure l is a detail viewin perspective of my improved building-block. Figs. 2 to.5,;-ii1clusive, show a number of different arrangements of the block that may be The same reference characters indicate the zontal joints do not go through the wall.

employed in the formation of walls therefrom.

same parts in all the views.

Let A designate myv improved building-' block in its entirety. This block consists of a body part A, end projections A and an- The said pro-- jections extend from :theinner surface of the block'and are of a height equal to half that of the body of the block. The projectionv A is' equidistant from the projections A and is twice the thickness of either projection A the projections A being of equal thickness. In referring to thethickness of the projections the'distance through them measured on a horizontal line lengthwise of the block is intended.

When the blocks are used in the construction of walls, they may be combined in a variety of ways. ,As shown in Fig. 2, two of the blocks ares'o placed that their projections interlock and coincide vertically, the two united blocksoccupying reverse positions on oppo-' site sides of the wall. The two block members A when united as just explained form a duplex blockhaving' rectangular sides and ends. These duplex blocks are placed end to end, and they are arranged in vertical having a height equal to courses to break joints. (See Fig. 2.) This figure shows the wall bonded in courses with horizontal joints extending through the wall, the blocksbreaking joints in alternatecourses.

In the construction shown in Fig. 3 the wall is formed by placing the blocks A end to end on opposite sides of the'w'all. In this case the projections interlock, as in-Fig. 2, the

only difierence being the arrangements for breaking. the joints. By virtue ofthis arrangement the adjoining'end projections of any two blocks interlock with and engage the central projection of the opposite block or the block on the opposite side of the wall. In this view the wall is bonded in courses with horizontal join ts extending through the wall, the blocks on' one side of the wall breaking joints with those on the oppositeside and also with each other.

In the construction shown in Fig. 4 the blocks: are vertically staggered on opposite sidesof the wall, whereby they are made to break joints horizontally. This construction shows a pier one block in length with the horizontal joints broken, the inner block lapping on the outer block, so that the hori The wall construction shown in-Fig. 5 is a combination of the arrangements-shown in Figs. 3 and 4, whereby the blocks A are vertically staggered and arranged to break joints both horizontally and vertically. This view shows a portion of a wall with the blocks on the inner side of the wall. breaking joints endwise with the blocks on the other side of the wall. so that no horizontal joint extends through the wall.

Having thus described my invention, what i I claim is l. Abuilding block or member coniprisinga body part having end and intermediate pro jections extending therefrom at right angles to the body of the block, the said projections half that of the body of the block.

2. A building -block comprising a body part having end and intermediate projections ex-. 1

tending therefrom at right angles thereto, the saidprojections having a height equal to half thatof the body'of the block, the intermediate projection being equidistant from The horizontal joints are broken,

the end projections and of twice the thickness of the end projections measured in a horizontal line extending lengthwise of the block. r

3. A wall composed of blocks having projections extending at'right angles to the body of the block and of less height than the body part,tl1e said blocks being reversed and united to form opposite sides of a wall, the projec-.

tions being arranged to coincide and interlock, and the courses being arranged one above another to break the vertical joints.

-t. A Wall composed of building-blocks having a body part provided with projections extending at right angles thereto and ofa less height than the body part, the said blocks having their vertical position reversed on opposite sides of the wall, and their projections being interlocked to break the V61" tical joints of a single course.

5. A wall composed of building-blocks having a body part, and projections extending at right angles to thebody part and of half the height of the body part, the blocks being vertically arranged in stepped or staggered fashion, to break the horizontal joints of the vertical courses.

6. A wall com posed of building-blocks having a body part and projections extending at right angles to the said part and of half the height thereof, the blocks being Nertically arranged in stepped fashion, to break the horizontal and vertical joints of the different courses.

In testimony whereof I affix my signature in presence oftwo witnesses.

JOHN ALBERT FERGUSON.
